Whenever I try to compile my code for this function my compiler keeps throwing

projectB.c:31:15: error: conflicting types for ‘returnDegree’

projectB.c:19:17: note: previous implicit declaration of ‘returnDegree’ was here

```
#include <stdio.h>
#include<math.h>
int main(){
double sanantonioLat;
sanantonioLat = returnDegree(29.0,25.0,51.0);
printf("blah %f\n" , sanantonioLat);
return 0;
}
static double returnDegree(double degree, double minute, double second)
{
double solution;
solution = degree + (minute * (1.0/60.0)) + (second * (1.0/60.0) * (1.0/60.0));
return solution;
}
```

All of my variables are of type double so why is it complaining about it?

I thought maybe there could be a predefined variable for degree in math.h (below all of this code I've written a very long algorithm for finding the shortest distance between two points on the globe which is why I need the sin, arctan2, etc. from math.h). But I found no such variable.

Please help :) .
